Tīmeklis2024. gada 20. marts · Fetal hemoglobin (Hb F; alpha2gamma2) is the major hemoglobin in fetal red blood cells (RBCs) during gestation and constitutes 60 to 80 percent of total hemoglobin in the full-term newborn. By approximately 6 to 12 months of age, Hb F is almost completely replaced by adult hemoglobin (Hb A; alpha2beta2). The KB test is the standard method of quantitating fetal–maternal hemorrhage (FMH). It takes advantage of the differential resistance of fetal hemoglobin to acid. A standard blood smear is prepared from the mother's blood and exposed to an acid bath. This removes adult hemoglobin, but not fetal hemoglobin, from the red blood cells. Subsequent staining, using Shepard's method, makes fetal cells (containing fetal hemoglobin) appear rose-pink in color, while adult red blood c… the starry love cap 39 sub español
